Fireplace and Chimney CAD Blocks

Three masonry CAD blocks for the hearth: a 36in and a 48in fireplace, each drawn as the splayed firebox and the full masonry surround it really needs - 56 and 75in of wall for a 36 and a 48in opening - with the hearth extension projecting into the room, and a 24x48in chimney mass hatched as the plan cut with its flue drawn as the void it is. A hearth is a wall fixture with a projection, not a room; these are the blocks that let a plan say so. Free DXF downloads drawn to scale in inches.

The hearth drawn as masonry, not as a rectangle.

Firebox opening, masonry surround and hearth projection kept apart, because they are three different dimensions. Open one in the editor or take the DXF.
